As Su Fengnuan expected, the Northern Zhou Dynasty did not attack the city during the day, and there was no movement in the Northern Zhou camp thirty miles away.
The fire dragons in the ravines of the four cities of Yanbei City dug continuously day and night, and finally completed the work in the evening according to Su Fengnuan's request.
According to Su Fengnuan's idea, Su Zhen arranged for people to fill the ravine with dry firewood, oilcloth and other flammable materials, and waited for the Northern Zhou soldiers to attack the city before setting fire to everything in the ravine.
During the day, Chen and his men went out to cut a large amount of dry firewood before the Northern Zhou army attacked the city, and stored it for a few days.
In the evening, everything was ready, waiting for Chu Han to come to attack the city with the soldiers of the Northern Zhou Dynasty.
Sure enough, after Chu Han withdrew his troops yesterday and returned to the camp at the rear, he ordered people to find out how many reinforcements had arrived from the western border. After exploring the horses for a while, he reported back that only tens of thousands of soldiers and horses had come from the western border, and they had already entered Yanbei City, and no other soldiers and horses were seen within dozens of miles.
Chu Han knew that he had fallen for the old trick of setting up a suspicious formation, and said angrily, "It must be the vanguard of the western border soldiers and horses. Let's explore again and explore a hundred miles."
"Yes." Tanma continued to explore westward.
It wasn't until the evening of the second day that the horse scouts reported that there were no soldiers and horses from the western region two hundred miles away. Only then did Chu Han know that there was no army from the western region at all. He said angrily, "Pass down the order and send troops to attack the city!"
With an order, the soldiers and horsemen of the Northern Zhou Dynasty divided into four groups and attacked Yanbei City.
In the evening, after dinner, Su Fengnuan, Xu Yunchu, Chen Chen, Su Zhen, Zhang Lin and others waited in Wangjiao Tower.
When he saw the movement in the Northern Zhou camp, Su Fengnuan turned his head and said to Su Zhen, "Second Uncle, send an order to ignite the fire dragon in the ravine."
Su Zhen nodded, greeted Zhang Lin, and went down the Wangjiao Building together.
Standing on the Mong Kok Tower and looking around, Chen said, "This Mong Kok Building is really well built. It is comparable to a beacon tower. Standing on the highest point, you can see a hundred miles at a glance. If there is any movement on the North Monday, you will be the first to see it." Time to find out."
Su Fengnuan said, "Decades ago, Northern Zhou once sent a team of soldiers and horses into the northern border, but most of them were lost in the Wuwang Valley. Later, Yanbei repaired such a Wangjiao Tower to prevent Northern Zhou from Re-entry." After a pause, she said, "It's just a pity that although Yanbei knew about Bei Zhou's aggression in advance, the 800-mile rush still failed to send the news to Beijing immediately. into such a precarious situation.”
Xu Yunchu sighed, "Internal affairs are as fierce as a tiger. If there are no internal worries, why should we be afraid of external troubles?"
Su Fengnuan nodded.
The statement said angrily, "The emperor is too benevolent. In my opinion, those who are corrupt and pervert the law, collaborating with the enemy and traitor should be killed!"
Xu Yunchu glanced at the statement, but said nothing.
Su Fengnuan looked at the angry statement, and secretly sighed, he must not know what An Guogong did, right
The cavalry of the Northern Zhou Dynasty moved out quickly, and they arrived outside the four cities in a short time. At this time, Su Zhen had ordered someone to ignite the fire dragon in the ravine, and raging flames gushed out from the ravine, immediately surrounding the gates of the four cities in Yanbei into a circling fire dragon.
When the soldiers and horses of the Northern Zhou Dynasty arrived, Chu Han reined in the horse's reins, and looked at Yanbei City surrounded by fire dragons, his face darkened immediately.
The deputy general said in amazement, "This... this Su Fengnuan knows that Yanbei City cannot be kept, and wants to set fire to Yanbei City to set itself on fire?"
Chu Han said angrily, "Where did she set herself on fire? Didn't you see that the ravine was dug a few feet away from the city gate? This is obviously to prevent my Northern Zhou soldiers from attacking the city."
The lieutenant was even more shocked, "This... When did this fire ditch outside the four cities of Yanbei City be dug?"
Chu Han said with a sullen face, "I fell into Su Fengnuan's trick, thinking that the army from the western region was coming, and in order to detect the army from the western region, I planned to deal with Su Che, but I didn't expect that there were only tens of thousands of soldiers and horses, and I gave her time to dig out the fire. ditch."
The deputy general said in surprise, "We can't get past such a fire ditch. We must find a way to extinguish the fire." After saying that, he said to Chu Han, "Second prince, let's put out the fire with water."
Chu Han became even angrier when he heard the words, "The nearest water source is dozens of miles away, how can we attract the fire?" After saying that, he looked at the blazing flames, and said, "The order, the soldiers and horses of the Northern Zhou Dynasty are waiting for the fire to be extinguished. I Let's see how much dry firewood there is in Yanbei City, how long is it enough for Su Fengnuan to hold me back with fire?"
With an order, the soldiers and horses of the Northern Zhou Dynasty besieged Yanbei City and waited in formation outside the fire dragon in the ravine.
Su Fengnuan could see clearly from the Mong Kok Tower. Seeing that Chu Han was gathering his troops and waiting for the fire to be extinguished, she curled the corners of her mouth and said with a smile, "I'm afraid he won't wait, as long as he waits, that's fine. Firewood and other things are enough for him to wait for three days and three nights. After three days, the reinforcements from the western region should also arrive."
Xu Yunchu nodded with a smile, "So, this strategy is well used."
Shen Shu praised, "You are the only one who can come up with such a scheme. It doesn't cost a single soldier to make Chu Hangan stare at nothing."
Su Fengnuan smiled and said, "It's not impossible. Filling earth and rocks can put out the fire. It's just that Chu Han's expedition to Yanbei, except for soldiers, horses, food and grass, there is no other iron shovel for digging. Yanbei City The radius within fifty miles is flat. If he wants to transport rocks to cover the fire, he will have to toss fifty miles, which is difficult. Therefore, there is no other way but to wait. I am sure that he can only wait, so I use this strategy to delay him. "
He stated, "But the dry firewood we have in reserve is not enough for three days and nights, right? The dry firewood I brought out with people, if it burns like this, is only enough for one night. Is there so much dry firewood in the city?"
Su Fengnuan smiled and said, "It's already Mid-Autumn Festival! The climate in Yanbei is already as cold as the capital city. After late autumn, every household in Yanbei will start to heat up. The people will prepare winter dry food in advance on the eve of Mid-Autumn Festival. Firewood reserves. The dry firewood in the homes of the people in the entire Yanbei City can be burned for three days and three nights."
The statement praised and gave a thumbs up, "You are amazing! You have thought of it all! Hahahaha..."
Su Fengnuan smiled, "Chu Han still doesn't know Yanbei well enough. He must think that the dry firewood in our city is enough for one night, but he doesn't know that we have three days' reserves. After he guards for three days, the Northern Zhou soldiers must be exhausted. When reinforcements from the western border arrive, it is time to take action against him."
The statement is gearing up, "At that time, I will also go to the battle to meet Chu Han."
Su Fengnuan laughed, "Chu Han is not only good at riding, archery, marching and fighting, but also has excellent internal martial arts, which is not much worse than the masters of the rivers and lakes. You don't know internal martial arts, so you should be more disciplined then."
The statement suddenly died down, "This Chu Han is so powerful?" After saying that, he wondered, "But I haven't seen how powerful he is."
Xu Yunchu laughed from the sidelines, "You haven't seen how powerful he is, but you've only seen him suffering everywhere. That's because he met Miss Su. If it were someone else, Yanbei City would have been captured by him last night!"
Chen Chen scratched his head and nodded sincerely, "That's right! It's his bad luck that he met Miss Su."
At this time, Su Zhen walked up to the Wangjiao Tower quickly, and smiled at the three of them, "Yuanyuan's strategy really worked, the Northern Zhou army didn't attack the city, our soldiers worked so hard to dig ditches, we were so tired that our hands were almost useless, it was worth it. "
Su Fengnuan said with a smile, "Second uncle, arrange for the soldiers on duty to be stationed at the four city gates, and change a group of people on duty every four hours. Whenever the fire in the gully is small, they will go from the city wall to the gully. Throw in dry firewood, and keep the fire burning in the ravine. Soldiers who are not on duty, all rest."
Su Zhen said, "Okay, I'll pass the order later!"
Su Fengnuan smiled and said, "You are tired too, go and rest later, I will watch the city guard here tonight."
Su Zhen was indeed tired. He hadn't had a rest day and night for many days, and he didn't refuse when he heard the words, so he nodded.
After Su Zhen left, Xu Yunchu said warmly to Su Feng, "Let's play a game of chess, and I will defend the city with you tonight."
Su Fengnuan smiled, and said briskly, "Okay, light the stove, make a pot of tea, and warm two pots of wine. I'm also in the mood now."
Chen Chen looked at the two, rolled his eyes, and immediately said, "I'm watching chess."
Su Fengnuan glanced at him with a faint smile.
Chen Chen scratched his head, feeling a little embarrassed to be seen through by Su Fengnuan, "Well... I can't sleep... I promise I won't talk while watching chess, and I won't disturb you playing chess."
Xu Yunchu smiled knowingly.
So, that night, Su Fengnuan and Xu Yunchu set up a chess game and played against each other upstairs in Mong Kok. He stated that he sat on the sidelines, that he was talented in business, and also witty and talented in marching and fighting, but he only knew how to play chess. Not fine. But Su Fengnuan and Xu Yunchu are both masters of chess, so it is said that it is naturally exciting for masters to play tricks. Therefore, the statement was read with relish and without sleepiness.
Outside the city, the army of the Northern Zhou Dynasty waited for the dry diesel cloth and other things in the city to be exhausted, and they were always energetic, preparing to break through the loose openings and attack the city in one fell swoop.
Chu Han sat on the horse, thinking that if there was a breakthrough, she would let Su Fengnuan die this time.
One night, Su Fengnuan and Xu Yunchu played three games of chess, and all three games ended with draws. But at dawn, after Xu Yunchu dropped a piece, he smiled at Su Fengnuan, "I lost! I'm not as good at chess as you are!"
Statement shouted from the side, "No! Isn't this a draw? Where did you lose? Could it be that my eyes are blurred? Isn't this a draw?"
Xu Yunchu sighed, and said with admiration, "Miss Su gave in. Although the second son looked like a draw, he actually lost in the middle of the chess game early in the game."
Statement looked at him, "No way? Why didn't I see it?"
Xu Yunchu said with a smile, "Miss Su took one move and saw ten moves. Halfway through the game, she had completely controlled the initiative, and I could only follow the game she set up step by step to the draw she wanted. , there is no other way to go. Isn't this a loss?"
Statement froze for a moment, then looked at Su Fengnuan.
Su Fengnuan chuckled, put down the jug, and said to Xu Yunchu, "Uncle Xiaoguo is too modest! From the perspective of chess, Uncle Xiaoguo has an elegant character. Although I set up a game, there is not only one way to go, you just choose This is the most gentlemanly way. This is not a loss."
Chen Chen patted his head when he heard the words, "Oh, I'm really stupid. I watched the chess game all night, but I didn't see it. I'm so stupid! I'm so stupid!"
